Estrous synchronization is typically associated with artificial insemination (AI) programs, and is therefore often viewed as impractical or impossible to use within natural-service herds. With 92% of beef herds exclusively implementing a natural-service breeding environment (NAHMS, 2009), estrous synchronization has a place in natural-service breeding systems if implementation can be adapted into normal daily tasks.
